2021 arXiv   pre-print
How to query zero-streaming cameras efficiently? Our response is a camera/cloud runtime system called DIVA.  ...  For efficiency, we advocate for these cameras to be zero streaming: capturing videos to local storage and communicating with the cloud only when analytics is requested.  ...  . • Zero streaming, a new model for low-cost cameras to operate on frugal networks while answering video queries. • Two novel techniques for querying zero-streaming cameras: optimizing queries with accurate  ...

Composing semantic services in open sensor-rich environments

Jie Liu, Feng Zhao
2008 IEEE Network  
Most sensor networks today are deployed for a single purpose. They are designed for either data collection [8] or a domain-specific application (e.g. [6],[9],[10]).  ...  Semantics services process input streams and generate new streams, possibly with different semantic interpretations. They can be  ...  A semantic service is a transformation of semantics streams. It takes zero or more input streams and produces one or more output streams.  ...

Towards service-oriented continuous queries in pervasive systems

Yann Gripay, Frédérique Laforest, Jean-Marc Petit
2008 Ingénierie des Systèmes d'Information  
Relations, data streams and services can be homogeneously queried using a SQL-like language, on top of which query optimization can be performed.  ...  In this paper, we tackle the definition of continuous queries combining standard relations, data streams and services in a declarative language extending SQL.  ...  The actual query is shown in Table 11 : it involves the stream "sensor", the virtual table "camera", and a COLLAPSE clause.  ...
